Biography

Mary Louise Weller was born in New York City and was raised in Los Angeles' Westwood area. The onetime top New York model made her film debut with an uncredited role in the 1973 Al Pacino cop drama Serpico. In 1978 Weller starred as a beautiful marine biologist in the made-for-TV film, Hunters of the Reef and then as professor Andrew Prine's college student lover in the haunted house horror film The Evil. Mary Louise achieved perhaps her greatest enduring cult movie popularity with her performance as snooty and uptight sorority snob Mandy Pepperidge in the hit comedy Animal House. In an interview with James M. Tate, Weller admitted that she wasn't the first choice for the part of Mandy Pepperidge.

After Animal House Weller went on to play the sole non-suicidal character in The Bell Jar, Martin Kove's wife in the monster movie Blood Tide, Chuck Norris' girlfriend in the martial arts action film Forced Vengeance, and a small part in Larry Cohen's tongue-in-cheek monster-on-the-loose film Q - The Winged Serpent.

She acted in several plays in New York and wrote the play Four Alone, which was performed at the Greenhouse Theater in Pasadena. Moreover, Mary Louise trained with the U.S. Equestrian Team as a teenager and has participated in horse-riding competitions. Weller tried to get a movie based on her own original script made about jockey Mary Bacon, but it never materialized. She's a first cousin to writer Sheila Weller, who mentioned Mary Louise in her 2003 book Dancing at Ciro's. As of 2007, Mary Louise Weller is retired from acting.

According to Dancing at Ciro's, Mary Louise Weller is of Lithuanian Jewish descent.
